John Frieda Brilliant Brunette Luminous Colour Glaze only takes one 3-minute application and can be applied right in your shower. The easy-to-apply treatment uses Shine Enhancers to create a highly reflective surface, as well as pore menders to fill in damaged areas along each strand of hair, helping to create a smooth, more even texture for brunette hair. A hint of glossy, brown colour is added to all shades of natural hair color, colour-treated, and highlighted hair - and continued use only intensifies the hue. The result is rich, luminous, glossy hair. Satisfaction Guarantee.
